OPERATION
TO THE NEW OPERATOR OR OWNER
The Buhler Farm King 45 Series Rotary Tiller is a machine that combines the primary
and secondary tillage operat ion into one machine. It breaks up the soil and prepares
the seed bed in one pass. Rotational power to the rotor is provided by the tractor PTO.
Be familiar with the machine before starting.
It is the responsibility of the owner or operator to read this manual and to train all
other operators before they start working with the machine. Follow all safety
instructions exactly. Safety is everyone's business. By following recommended
procedures, a safe working environment is provided for the operator, bystanders
and the area around the work site. Untrained operators are not qualified to
operate the machine.
Many features incorporated into this machine are the result of suggestions made by
customers like you. Read this manual carefully to learn how to operate the machine
safely and how to set it to provide maximum field efficiency. By following the operating
instructions in conjunction with a good maintenance program, your Tiller will provide
many years of trouble-free service.
MACHINE COMPONENTS
The Buhler Farm King 45 Series Rotary Tiller consists of a rotating drum that is
equipped with bent blades for breaking up and leveling soil. The blades are turned
through the soil while the machine moves over the working area. A Drag Shield is used
to maintain a level seedbed. Rotational power to the drum is provided by the PTO on
the tractor. The power is transmitted through the gearbox in the center of the machine
to the chain drive down the side. The A-frame can be moved to offset the machine.

Although there are no operational restrictions on the Tiller when used for the first time, it
is recommended that the following mechanical items be checked:
A. After operating for 1/2 hour or after completing 1/2 acre:
1. Check all nuts, bolts and other fasteners. Tighten to their specified torque
level.
2. Check that the blades are in good condition and bolted securely to the
rotor.
3. Check the oil level in the gear box. Add as required.
4. Check that the PTO driveline shield turns freely.
5. Lubricate all grease points.
B. After operating for 5 hours and 10 hours:
1. Repeat items 1 through 5 of Section A.
2. Then go to the regular service schedule as defined in Section 5.
Efficient and safe operation of the Rotary Tiller requires that each operator reads and
understands the operating procedures and all related safety precautions outlined in this
section. A pre-operation checklist is provided for the operator. It is important for both
personal safety and maintaining the good mechanical condition of the Tiller that this
checklist is followed.
Before operating the machine and each time thereafter, the following areas should be
checked off:
Lubricate the machine per the schedule outlin ed in the Service and Maintenance
Section.
Use only a tractor of adequate power and weight to pull the machine.
Check that the machine is properly attached to the tractor. Be sure retainers are
used on the mounting pins.
Check the oil level in the gearbox. Add as required.
Check that the PTO driveline shield turns freely and that the driveline can
telescope easily. Clean and lubricate if required.
Before using PTO: Slip Clutch PTO’s are shipped with the slip clutch
disengaged. Socket set screws in the clutch assembly must be fully backed out
to engage the clutch.
Check the blades. Be sure they are not damaged or broken and are bolted
securely to the rotor. Repair or replace as required.
Remove any entangled material on rotating parts.
Install and secure all guards, doors and covers before starting.

PRE-OPERATION CHECKLIST
45 Series Rotary Tiller
EQUIPMENT MATCHING
To insure the safe and reliable operation of the Tiller, it is necessary to use a tractor
with the correct specifications. Use the following list as a guide in selecting a tractor to
use on the machine.
1. Horsepower: Use Table 1 as a guide in selecting the tractor horsepower
appropriate for your width of machine. Use only small Agricultural tractors on this
machine.
Table 1 Horsepower vs. Width
Model Width Horsepower
4560 60 inches 45 max.
(1.5m)
4572 72 inches 45 max.
(1.8m)
2. 3 Point Hitch:
The Tiller is equipped with a Category 1, 3 point hitch. Be sure the tractor 3 point
hitch is in the Category 1 configuration. A Category 1 Quick Hitch will fit on the
Tiller.
Install the lift arm blocks or shorten the stop chains to place the arms into the
non-sway configuration. Refer to the tractor manual for details.
3. Load Sensing Hydraulics:
Many newer tractors are equipped with "Load Sensing" hydraulics. It is the
responsibility of the operator to set the tractor hydraulic system to provide "float"
on the 3 point hitch.
The float feature will allow the machine to follow the ground contours during
operation.
4. PTO Shaft:
The tractor must have a 1 3/8" 6 spline 540 RPM PTO shaft to fit the driveline
shaft supplied with the machine. Do not use shaft adapters or operate at any
other speed.
It is not recommended that a tractor with variable speed PTO's be used on the
Tiller. Operating at speeds faster than 540 RPM will overload the drivetrain and
lead to early failures. Attach the safety chains supplied with the PTO shaft,
allowing sufficient slack for the Driveline during turns and operation. Check
booklet attached to the PTO for instructions.
ALERT: Do not exceed the recommended horsepower levels. The use
of horsepower will void the wa rranty.
